Description:

FIELD OF THE INVENTION

[0001] The present invention broadly relates to mobile Location-Based
Services (LBS) even though geo-location coordinates are not required for
invention. Specifically, the invention allows for a single mobile
application to adapt its functionality, in real-time, based on context
data associated with multiple providing locations.

BACKGROUND AND RELATED ART

[0002] As mobile applications become more and more widespread amongst
smart phones such as the iPhone, Blackberry, Nokia N Series, LG POP,
Samsung Galaxy, Palm Pre, Google Nexus One, and more recently new tablet
computers such as Apple's iPad, users will need to manage an
ever-increasing number of applications inside these devices.

[0003] Even though phone makers have began to provide User-Interface (UI)
solutions to allow users to group, access and launch their applications
faster and more easily, these become necessarily inefficient as the
number of applications grows dramatically inside the device, hence
requiring the user to manually arrange or delete applications according
to their own usage. Furthermore, once many applications have been
installed on the mobile device, it becomes harder for a user to remember
which set of applications can be used in a particular setting, at a
particular time and for a particular use or context.

[0004] Certainly, there are mobile applications implementing Augmented
Reality techniques and more generally Location-Based Services which, if
and only if the user agrees to be geo-localized, can bring a plurality of
information or services based on that location. Yet, these applications
are designed to gather information from data associated with GPS, GSM
triangulation techniques and the like to display a predefined UI based on
that data, which necessarily makes it difficult for said applications to
perform an entirely new functional behavior based on what the user can do
in the particular context.

[0005] U.S. patent application (Ser. No. 12/041,971) describes a method
for computing a novelty index value based on the location of the user.
The method specifically allows to display on the mobile terminal
appropriate recommendations or personalized information determined by
where the user is or how often he has been in a particular location.
Because the resulting display is configured from applications that are
"set in the device", this limits the range of possibilities to the ones
that have been pre-installed in the mobile phone.

[0006] Other systems such as mentioned U.S. Pat. No. 7,058,895 describe a
method and a conceptual structure allowing users to customize their
mobile terminal based on their own preferences. This method requires the
user to manually pre-define his contextual preferences by using a PC
application to build the said conceptual structure by adding nodes to a
conceptual graph. Among other this method presents the disadvantages of
forcing the user to use a PC application in order to benefit from the
adaptive UI on the mobile device therefore complexifying the process for
the user while increasing the time to operate.

[0007] U.S. Pat. No. 7,590,681 describes a method and a system for
managing and delivering web content for internet appliances. The patent
involves letting a user customize the display of web content on an
internet appliance such as mobile phone, PDA, and the like.

[0008] This method forces the user to manually configure his device and
the type of content to be displayed when using this device, adding
complexity and Lime to operate for an average mobile-device user.

[0009] US Patent 2010/0042463 describes a software or hardware facility
for providing an enhanced shopping experience. The proposed invention
determines user characteristics such as location (location, population
density, etc.) or demographic (age, gender, occupation, etc.) and
consolidates these results with the mobile device's characteristic such
as its location or its identifier. The resulting data is used to retrieve
product and shopping information based on advertiser-defined parameters.

[0010] The invention of the above mentioned document uses different
context modules in order to determine which is the best product offer to
display on the user's mobile device. However, the invention relates to
product queries in relation to user and mobile characteristics and
requires the device to have previously stored a delivered message which
implies that the client software needs to have been pre-programmed to do
so. This further implies that no application other than the ones capable
of interfacing with said software or hardware facility can be operated by
the user contrarily to what is claimed by the present invention.

SUMMARY OF THE INVENTION

[0011] The method, and system of the invention for delivering
context-based mobile applications in real-time or near real-time,
eliminates the need to search, install or launch relevant applications
based on their availability at a particular location and according to a
particular context. This overcomes the technical limitations and/or
disadvantages of the above systems.

[0012] Because the application is never resident on the device, the
proposed method solves the problem of having to remember which
application can be used in a specific environment and whether it has
already been downloaded. The system also eliminates the need to find the
application in question on the mobile device in order to launch it.

[0013] Furthermore, the method according to the invention enables the
automatic substitution of content on the mobile devices' display as the
user moves from one context to another etc.

[0014] The invention more generally describes a method for delivering a
plurality of individual mobile applications based on the user's
contextual environment. Specifically, the invention allows for a single
application to adapt its functionality, in real-time, based on context
data associated with the providing location, and hence giving the user
the ability to interact with an infinite number of different applications
without the need to search, install or launch any of them.

[0015] In other words, the method allows delivering of a plurality of
applications to mobile devices, based on contextual data available in the
immediate surrounding of a user's location. In a preferred embodiment,
the method uses a system having a contextual engine application installed
on the mobile devices, for retrieving the contextual data and displaying
the applications, several contextualizer devices being located in
different places and being arranged to connect wirelessly to the mobile
devices present in the surroundings to deliver the appropriate
application to the mobile device.

[0016] It should be understood that by contextual data it could be local
or temporal, and that one should understand on every broad sense,
localization, time, user' activity (i.e. for example, shopping, watching
TV, etc), identity or any other data related to the specific context in
the environment of the mobile device, which could be non limitatively the
weather, the inside or outside temperature through a local sensing
device, the character of the visit (activity) of the user of the mobile
device in the localization based on various criteria such as the RFM
criteria (Recency, Frequency, Monetary) etc.

[0017] An other aspect of the invention is to provide a method for
delivering temporarily a plurality of software applications each based on
respective contextual data, to one or more wireless mobile end-user
devices, by using a single application called contextual engine
pre-installed in said mobile devices, said delivery being limited to the
immediate vicinity of specific locations comprising the steps of [0018]
(i) receiving on a local device located in the vicinity of one of said
specific locations a remote request from one of said mobile end-user
devices located near said local device for retrieving one of said
plurality of applications related to its respective contextual data,
[0019] (ii) receiving on said local device said application from a remote
server, [0020] (iii) delivering automatically from said local device
exclusively said software application to said mobile end-user device via
a wireless connection, and [0021] (iv) displaying said application on
said mobile end user.

[0022] By immediate vicinity one should understand within a few meters to
two or three hundred meters, advantageously fifty to sixty meters.

[0023] A specific location should be understood very broadly. It could be
a store, a parking lot, an office building, a gallery, an apartment, a
house, etc. . . .

[0024] Advantageously the applications are stored on at least one virtual
internet server.

[0025] In preferred embodiments, not limitatively listed hereafter:
[0026] the mobile devices are mobile phones; [0027] the contextualizer
devices are wireless routers; [0028] the contextual engine is a native
application installed on the mobile device; the contextual engine enables
the delivery of applications without requiring the user to search,
install or launch said application(s); [0029] a web-based administration
module on said virtual server is used to create and manage a network of
contextual environments whereby a web-application can be delivered in
accordance with different parameters defined by an operator; [0030] the
applications are developed using a graphical application builder tool
connected to said virtual server; [0031] the contextualizer devices are
connected to the internet directly or via wired routers; [0032] the
contextualizer device contains a specific firmware programmed according
to the invention; [0033] the contextualizer devices comprise Wifi antenna
and/or an RFID antenna; [0034] the contextualizer device is embedded
within an internet appliance such as a TV set-top box, internet-enabled
TV, home router, printer, media center or kitchen appliance; [0035] the
firmware program restricts access to a range of IP addresses defined in a
database administration console stored on said virtual internet server;
[0036] the firmware program returns a Unique Device ID once the wireless
connection between said mobile device and said contextualizer device has
been established; [0037] the UDID is the UPnP ID of said contextualizer
device; [0038] the UDID is the MAC address of said contextualizer device;
[0039] the web-application comprises one or many components that can be
saved as dynamic cookies (which can expire or be automatically updated)
inside said contextual engine application; [0040] an expiring period
(date and time) is associated to said components preventing the end-user
from operating this component once expired. The association is made
through an administration console on the virtual server; [0041] operating
an expired component requires the end-user to extend said expiring period
through a transaction; [0042] the transaction involves sharing the said
component via a social network, purchasing or trading points in exchange
for extending said expiring period; [0043] the method further comprises
probing for a different UDN corresponding to a switch in contextualizer
device and displaying said appropriate web application or component;
[0044] the method further comprises tracking the time spent by the
end-user in a particular zone covered by said contextualizer and storing
the associated activity from said web application or said component.

[0045] Another object of the invention is also to propose a system for
managing, delivering, displaying and interacting in real-time with mobile
device applications based on contextual data available at the user's
location according to the method here above mentioned.

[0046] Advantageously the user implicitly agrees to have the
information/application "pushed" to him/her since he/she deliberately
launches the application without receiving any previous message and all
transactions and tracking are anonymous or otherwise explicitly
authorized by the end-user.

[0047] Advantageously a web application component is text for instance)
can be modified by a third party independently from the main application
(collaborative marketing) in order to update the context of a particular
location.

[0048] In another advantageous embodiment, said components can update the
web application automatically via an external data source such as an RSS
feed, an instant message, a sensor output, or the like.

[0049] Another object of the invention is to provide a process and a
system where there is no need for the user to manually switch access
points, no need to enter security key, where when the user exits the
"context zone" the application is no longer available which adds to the
security level, especially when using a financial transaction.

[0050] With the invention it will be possible to launch (as a setting
option) an existing application based on location. An other object of the
invention is to propose a contextualizing device which can tell the
contextual engine to display only the applications that can be used in
that particular location.

[0051] With the invention the exact same architecture can be used to
deliver context-aware content for any web-compatible device (PC, Tablet,
PDA, game console).

[0052] It will be obvious for the man skilled in the art that important
differences exist between the contextual engine of the invention and a
browser.

[0053] Web browsers such as Internet Explorer, Safari, or Firefox can
automatically display the home page of a web site once connected to the
internet. Nevertheless, said browsers can only be set to access a
specified URL either defined by the access provider or the user but are
not capable of integrating or combining data provided by other local
wireless technologies such as RFID, Bluetooth, local sensors or the like.

[0054] More particularly, a web browser does not include any means for
automatically detecting that the user is switching to a new wireless
access point, making it difficult to substitute a new UI based on new
context, which is one of the crucial aspects of the invention.

[0055] Moreover, a web browser is meant to allow the end-user to explore
an unlimited number of web destinations. This is done by providing a URL
or clicking on webpage links. Whereas the invention limits and locks the
web application to the user's current context in order to provide the
most relevant mobile service for the user's activity.

DETAILED DESCRIPTION OF EMBODIMENTS

[0068] As indicated above the present invention describes a method and a
system for managing, delivering, displaying and interacting in real-time
with mobile device applications based on contextual data available at the
user's location.

[0069] By mobile device we mean any mobile telephone, personal digital
assistant, notepad, tablet, netbook and the like equipped with wireless
connectivity such as 3G/4G, Wifi, Bluetooth, or NFC.

[0070] The method eliminates the need to search, install or launch
contextually or location-relevant applications by delivering these
applications on the fly, using a single application which we refer as
contextual engine hereafter.

[0071] Specifically, the invention allows said contextual engine to adapt
its functionality, in real-time, based on context data associated with
the providing location, and hence giving the user the ability to receive
and interact with an unlimited number of different applications modules.

[0072] The key feature of the invention is that said contextual engine has
no pre-defined functionality, it will inherit its "function" for example
from a distant server via a wireless access point which we refer as
contextualizer hereafter.

[0073] Unlike contextualized interactions described in the prior art, the
system described in the present invention does not require the mobile
device to "know" the type of data that is available at the location of
the user nor does it need to process this data using pre-installed
applications. Moreover the system does not necessarily rely on
geo-localization techniques in order to display applications that are
suitable for interaction at the user's location.

[0074] In one embodiment of the invention, FIG. 1 shows an overview
diagram of system 1 comprising a web based administration console 3
connected to a virtual server 5 via the internet 4--An administrator user
2 logs into said console to create and configure an operator 8. Said
operator is defined as a physical location including said contextualizer
device 9 which can be either directly connected to the internet 4 or
through a routing device 11. An online graphical application builder tool
7 is used by a content designer 6 to create a packaged web-application
which is then stored on said virtual server. Once the operator is created
with said associated web application, an end-user 14 can launch said
contextual engine on mobile device 13 in operator location setting 8. As
soon as the contextual engine is launched, a wireless connection 12 is
established between mobile device 13 and said contextualizer device using
a specific firmware module 10. Said firmware module checks the limit of
allocated IP addresses and the authorized DNS and Web content queries
through a firewall. If all operating conditions are met, the firmware
returns the device type of said contextualizer alone with its Unique
Device Name (UDN) to the mobile device. The associated web-application is
then instantly loaded from virtual server and displayed on the end-user's
mobile device.

[0075] FIG. 7. shows the basic control flow of said firmware module.

[0076] To decrease the time needed by the end-user to connect to
contextualizer and receive the associated web-application, a UPnP
protocol is used and the UPnP ID of the contextualizer device is
registered in the administration console. This registration procedure,
along with the automatic connection (aka "auto-join") to a known wireless
access point, allows the launched contextual engine to automatically
display said web-application without any action required from the
end-user.

[0077] FIG. 2 shows said administration console information model,
according to an embodiment of the invention. The console is used to
create and manage a network of contextual environments whereby
web-applications can be delivered in accordance with different parameters
defined by an operator.

[0078] The operator's name is set in said administration console. Once
set, one or a plurality of contexts can be associated with said operator.
The information model easily allows an operator to manage said network
across a wide range of contexts and geographic locations.

[0079] Four information blocks 22,24,25 and 26 can be instantiated
depending on how many contexts need to be created.

[0080] Block 22 allows to create the countries where the contextualizer(s)
need to operate. If the "global content" field is specified then the
associated web content in field "content zip" will be displayed first
upon launching the contextual engine. The "expiry" field determines when
this content should no longer be active (visible) on the mobile device.

[0081] Block 23 determines the type of users authorized to use the
administration console and the administrative rights thereof.

[0082] Block 24 allows to create all the regions and cities for each
country.

[0083] Block 25 defines the context such as the physical "place" where the
contextualizer devices are located, the "activity" such as the typology
of end-user interactivity (mobile couponing, product ordering, flash
sales, general information, social networking, etc.)

[0084] Block 26 is used to add and configure the contextualizer devices in
each "place" defined in Block 25. The UPnP ID of the contextualizer
device is entered in the field "Uid" which is used after the wireless
connection is established in order to fetch the right web-application
content on the virtual server.

[0085] FIG. 3 shows said online graphical application builder tool. A
template 32 is first chosen to define the resolution 31 of the mobile
device. A menu 33 of graphical elements and functional attributes allows
to define the layout and interactivity for each screen of said web
application by simply dragging elements from the asset areas 34,35 to the
screen 31. Once all, the content of the web application is created, it is
saved and uploaded using the "content zip" fields of said administration
console FIG. 2.

[0086] FIG. 4 shows the main flow diagram for said contextual engine. When
the end.-user starts the contextual engine 41, it tries to detect a
contextualizer device 42. If said contextualizer is detected then its UDN
(Unique Device Name) is sent to the contextual engine over a UPnP
protocol. To speed-up the discovery of the contextualizer, the contextual
engine enables the asynchronous notification of UMP packets. Once the UDN
44 has been transmitted, the contextual engine makes a request 45 to said
virtual server which send the context attributes associated with the
contextualizer to the mobile device. Said unique uPnP ID is requested
from the virtual server in JSON (JavaScript Object Notation) format. The
response is a list of unique content URLs that can be loaded into the
content view of the mobile device. Said content view is then ready to
load the first item in the list. If additional or updated content data is
available 46, then it is loaded from the virtual server into said mobile
device.

[0087] In another embodiment of the invention, the contextualizer device
is connected to a network switch via a wired-connection.

[0088] In another embodiment of the invention, a wireless-payment module
can be integrated within the web-application. This module allows the
end-user to remotely pay for a particular product or service based on a
virtual money exchange procedure described in FIG. 5

[0089] Prior to being able to use said module, the end-user 51 logs into
his personal internet profile 52 and adds money to his virtual wallet 53.
The method by which the end-user adds money to his virtual wallet uses
well known internet-based payment platforms such as PAYPAL or PAYTHRU and
is not described any further. Upon completion of this process, the
end-user can walk into a store 55, for example a coffee shop, equipped
with said contextualizer device 56 and launch contextual engine 57. The
store's contextual web-application is then received from virtual server
58 and displayed on mobile device 58. An example scenario of the ordering
process is described in FIG. 6. Once the end-user has validated his
order, the order is transmitted to the store's order queue on a tablet
device 59 as described in FIG. 10.

[0090] FIG. 6 shows a generic ordering scenario where upon launching the
contextual engine, the end-user receives a first screen indicating
general information and the specials of the day. By selecting the
contextual menu button 61, the end-user makes his selection(s) 62 among
the different menu items. Once the menu item is selected, he can browse
the different selections using standard "previous" and "next" buttons 63.
An "order" button allows to confirm the selection(s) and summary of all
ordered items are displayed on screen 64. To send the order to be
prepared the end-user presses "send order". A payment screen 65 is
displayed, showing the balance of the end-user and a "pay" button
terminates the order. Said order is then transmitted to the store's order
queue on a tablet device with the name and order number of the end-user.
When the order is ready, the order number is announced for the end-user
to pick-up.

[0091] In another embodiment of the invention, FIG. 8 describes a method
for associating a passenger's mobile device ID with an RFID chip embedded
inside a suitcase and FIG. 9 shows the associated system for alerting
said passenger when his suitcase enters the baggage claim carousel.

[0092] In FIG. 8, the end-user 81 scratches a label 83 on the suitcase's
identifying tag 82. The serial number revealed is then registered in a
secured web page 85 along with the name and address of the end-user. To
complete the registration of the suitcase, the end-user connects his
mobile device 84 to his PC using a USB connection. When he clicks on the
"register" button inside said secured web page, a local application on
the PC is automatically launched and reads the Unique Identification
(UID) number of the mobile device. If said UID is not already registered
on virtual server 5 then a data entry is created and the UID of the
mobile device is stored along with said serial number. If the UID already
exists, then the serial number is just added to the record. The name,
address and serial number are also registered on the suitcase
manufacturer's secured online database 86. This procedure can be extended
to additional users such as family members with their own RFID-enabled
suitcases.

[0093] In FIG. 9, the now registered passenger 91 can launch said
contextual engine 92 anon arrival at the baggage claim 96. The mobile
device 93 then performs the steps described in FIG. 3. to automatically
retrieve the web application from the contextualizer device 97. In this
particular embodiment of the invention, said contextualizer device
comprises two wireless communication channels. A first RFID reader 95 is
used to scan all suitcases as they are delivered at the baggage claim and
a second Wifi channel 95 for sending the web application to the mobile
device of the passenger. Once the web application is loaded, it displays
a message such as "YOUR LUGGAGE IS NOT YET ON THE BELT--Please wait . . .
". Once the RFID reader detects an RFID chip from an equipped suitcase,
the serial number is checked against said virtual server database entry
as well as said manufacturer's online database. If the serial number is
found then the message automatically changes to "SUITCASE OF <name of
passenger> HAS BEEN DELIVERED ON BELT # <belt number>".

[0094] FIG. 10, describes a preferred user scenario according to the
invention, where the end-user 102 enters a mall 101 and launches said
contextual engine 103. A plurality of contextualizer devices 105 are
arranged to cover said mall in such a way that the user automatically
connects to the nearest device as he walks through the space. The
distance between two said devices may not exceed 20 m with directional
antennas defining a small signal footprint 104 in order to facilitate the
change in context across multiple zones. In the present scenario, a web
application is delivered to the end-user, as described in FIG 4,
indicating a promotion in a specific store 106.

[0095] Another set of contextualizer devices 107 are equally positioned in
